If you've ever watched the show, Finding Bigfoot--something I watch when I can't fall asleep, you've probably noticed the show tends to go in a loop. They interview folks who claim to have seen Bigfoot, they go searching the wilderness in a dark, mostly creepy forest setting, and then--of course--there's some mysterious howls exchanged across the landscape and knocking on wood, which apparently is something Bigfoot would do to attract, well...another Bigfoot. They never find Bigfoot. They never find irrefutable proof of Bigfoot, but man, do they believe he's out there.
I know Bigfoot is not real. In all the years people have been chasing Bigfoot, there would be scientific proof, such as remains, DNA, or heck, even pictures that weren’t blurry brown smudges! Truth is, though, I want Bigfoot to be real. I want there to be a creature out there that's stayed miraculously hidden from humans for eons. I want the Yeti to dwell in the snowy mountains of Nepal. I WANT TO BELIEVE!
That's where we come in. As writers, we get to step in and bring our favorite "what-ifs" to life! We get to give them blood, and skin, and fur, and voices. Winged goblins, evil witches and scaled dragons take flight. Animals talk in a way we understand. Dwarves, gnomes, and fairies live in the shadowy places of forbidden forests, and we, as writers, have the honor of making the unreal very real.
This is how we know all dragons have a small soft spot on their underbelly. This how we know Santa can squeeze down even the smallest of chimneys. This is how we know house elves are bound as servants forever, unless given clothes by their owner.
And, this is how I know I'm born to write.
I want to believe. :)
